Application filed June is, 1917. Serial in). 175,146.

To all whom it may concern: Be it known that I, ADoLPH Raonnn, a citizen'of the United States, residing at Oakville, in the county of Litchfield and StittGjOf Connecticut, have invented a new and useful Improvement in Weatherproof Plural Lamp-Sockets; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and repre- Flgure 1 a view in side elevation of a weather-proof plural lamp-socket embodyingrmy invention.

ig. 2 a plan view thereof. Fig. 3 a view thereof in vertical section on the line 3-3 of Fig. 2.

Fi 4 a view of the metal parts as assemb ed prior to molding the body upon them. Q

Fig. 5 a detached perspective view of one of the closure disks.

Fig. 6 a detached, perspective view of the 1g. 7 a detail broken view showlng one method of coupling the arms of the screw plug shell and the arms of the lanip-receptacle screw-shells, together.

My invention relates to an improved plural or twin lamp-socket, the object being to produce at a low cost for manufacturc a plural lamp-socket constructed'with part cular reference to being weather-proof, to durability, to smoothness of exterior finlSllyELIld to avoiding the use of assembling screws or nuts.

With these ends in view, my invention constists in a plural lamp-socket havingncertain details of construction as will be ereinafter described claim.

In carryin out my invention as herein shown, I emp oy two lamp receptacle screwshells 4, 4, standing at an angle with respect to each other, made in one piece, having the adjacent edges of their upper ends united by each 5 and having the separated edges of their upper. ends formed with coupling arms 6 located diametrically op; posits t e said-web 5. .The said arms 6 are formed with tongues 7 adapted to p'ass through slots 8 in .arms 9 spending at and pointed out in theopposite points from the screw plug-shell I 10 which receives a plug 11 made of insulating material and having its upper end beveled as at 12 to project slightly beyond the contracted outer end 13 of the said shell 10. The plug 11 is formed with a central longitudinal perforation 14 for the reception of a long contact-pin 15 formed at its outer end with a contact-head 16 bearing upon the projecting outer end of the plug 11. The inner end of the contact-pin 15 passes through a perforation in the bowed upper end 17 of a bridge-piece 18. The lower ends 19 of the bridge-piece 18 are passed through radial slots 20 in heavy closure-disks 21 located in the extreme inner ends of the shells 4. The said lower ends .19 of the bridge-piece 18 are transversely bent to form yielding contact-fingers 22 with which the contacts of the lamps are engaged.

The metal parts above described, having been previously assembled as shown in Fig. 4, are, with the exception of the screw plug shell 10, incased in a molded body 23 of any suitable insulating material, which is applied plastic, under pressure so as to be I forced into the substantially triangular space .24 produced by uniting the shells 4. with the shell 10 in the manner described. The insulating material thus forced into the space 24, completely incloses the projecting inner end of the pin 15, the bridge-piece 18 and the coupling arms 6 and 9, whereby they are permanently positioned with respect to each other against possible displacement and are also protected against breakage in any use of the socket;-however rough. I should here call attention to the fact that the parts assembled as they are shown to be in Fig. 4, are tied together'as it were, against displacement when the-insulating material in plastic form is applied superior eficiency as a protective enve op,

putting the socket in the weather-proof class. As shown, the lower-ends of the hotly In a weather-proof lamp-socket, the com bination with a screw plug-shell and two lamp-receptacle screw-shells of means for electrically connecting the said shells, slotted closure disks located within the inner ends of the screw-shells, a contact pin passing through the said plug, contact-strips connected with-the said pin and entering the slots in the said disks, and a one-piece m01ded body inclosing the said screw-shells and filling the space between the said shells,

plu and disks, the said parts being assem led in spaced relation into a substantially unitary structure preparatory to the application of the molded body by which their spaced relations are permanently fixed and they are protected.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
